Under One Man had a total of five seasons. The first season began airing in 2016, with a total of 12 episodes. The story revolved around the encounter between the main characters Zhang Chulan and Feng Baobao. The second season was updated in 2017, and the animation production company was changed to Shanghai Painting Culture Communication Co., Ltd. The third season would be updated in 2020 and would be produced by Big Firebird Culture. The fourth and fifth seasons had already been broadcast, and the fifth season was currently being updated.
It's possible. If the first season of the anime based on a completed manga is highly successful and there's enough interest from both fans and producers, a second season can be made. However, factors like production costs and licensing issues can also come into play.
The three to five seasons of the anime,"Hero Mist", might contain 52 episodes, but the first and second seasons only had 52 episodes. It might be because of the difference in production companies or because of the distribution of episodes, there might be different episodes at different times. However, whether or not the specific number of episodes would change still needed to wait for the official announcement and confirmation.
It's hard to say which one is better. It really comes down to what aspects you value in a game. If you like complex farming systems, Story of Seasons might be for you. But if you enjoy a simpler, more story-driven experience, A New Beginning could be the choice.
